 This was tested on Windows 10 x64, with ScummVM 2.9.1 and a local build
 (mingw64/msys2) from recent master HEAD. The versions I have for the games
 are the Mac versions as extracted from the GOG files
 (syberia_en_2.0.0.1.pkg and syberia_2_en_1_0_0_gog_15710.pkg). I use the
 English language version.

 I have followed the instructions from the ScummVM wiki (I have done this
 before and the games used to work properly with ScummVM, at least for the
 first screens that I had tested).

 In ScummVM 2.9.1, I can add the games (`contents` folder) and launch them,
 but both get "stuck" (but not frozen) in the starting logo screen, the one
 after "Microids"; I think it says "KOALLABS". Music is still playing and
 apparently you can randomly click on the screen and "hit" the invisible
 "New Game" or "Continue" button because the engine thinks that it's
 showing the Main Menu. If I reach in game this way, or by loading an old
 saved game from the launcher, Kate's movement is too erratic (moving too
 fast at parts or almost teleporting) and there's some sound issues (like a
 sound effect quickly repeating on itself and sounding like noise). This
 was tested in the starting areas (hotel lobby with Momo and reception) of
 the game.

 In ScummVM 2.10.0git (local build with MINGW64/msys2 from master HEAD),
 the games get past the loading logo screen ok, and the main menu is
 showing properly, but in-game the icons for navigation/options are
 missing. There are no issues with Kate's movement or the music though,
 that I noticed.

 These issues do not seem to occur when testing with ScummVM 2.9.0 (same
 platform and folders), which points to a potential regression in the newer
 engine code.
